I am having trouble getting Kibana to connect to elasticsearch. The error I get is below;

plugin:elasticsearch@5.6.1 Request Timeout after 3000ms

Elasticsearch has been deployed via kubernetes and runs as a service called monitoring-es with a cluster IP of 100.63.124.194.

In my Kibana.yml file I have set the elasticsearch url as;

elasticsearch.url: "http://100.63.124.194:9200"

However I still get the same error. Is this the correct value or is there something I am missing?

Thanks
